Snezhnost [94]

To answer this question, try to solve the system of equations.  Start by plugging in "x^{2} +3x-7" in for y in the second equation:

x^{2} +3x-7-5x+8=0

<em>*Combine like terms*</em>

x^{2} -2x+1=0

<em>*Factor*</em>

(x-1)(x-1)=0

<em>*Set each term equal to 0*</em>

x-1=0

<em>*Add 1 to both sides*</em>

x=1


C) There is exactly 1 solution.


Hope this helps!!
